Check Digit Verification of cas no

The CAS Registry Mumber 215029-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,0,2 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 215029-48:
(8*2)+(7*1)+(6*5)+(5*0)+(4*2)+(3*9)+(2*4)+(1*8)=104
104 % 10 = 4
So 215029-48-4 is a valid CAS Registry Number.

Development of supramolecular organo-gel based on tripeptide skeletons

Azuma, Eriko,Kuramochi, Kouji,Tsubaki, Kazunori

body text, p. 680 - 684 (2010/07/15)

Boc-Ser-Val-Gly-OCH2Ph (31) showed high gelation abilities in the aromatic solvents, particularly in toluene. The minimum gelation concentration of 31 in toluene was 10 mg/ml, suggesting that 2500 molecules of toluene were immobilized by each m

THE USE OF PENICILLIN ACYLASE FOR SELECTIVE N-TERMINAL DEPROTECTION IN PEPTIDE SYNTHESIS

Waldmann, Herbert

, p. 1131 - 1134 (2007/10/02)

Penicillin acylase from E. coli (EC 3.5.1.11) accepts a broad range of N-phenylacetyl-dipeptide esters as substrates.The enzyme hydrolyses the N-terminal protecting group selectively at room temp. and pH=8.1 without affecting the peptide- or the ester-bonds.Alternatively methyl-, benzyl-, tert-butyl and allyl esters can be cleaved chemically leaving the phenylacetamido moiety intact.
